Objective: To analyze the association between postural balance and anthropometric indicators in elementary school students. Methods: This cross-sectional, descriptive and quantitative study included children enrolled in the first year of elementary school, of both sexes, in the age group of 6 to 7 years. Children with any physical or cognitive impairment, children who did not participate in all stages of the study evaluation, or those who failed to perform postural balance assessments were excluded. The children underwent a balance evaluation through a computerized dynamic posturograph, with sensory organization tests (TOSs) in six different sensory conditions. In order to verify the anthropometric indicators, the body weight and height measurements were evaluated for later calculation of the body mass index (BMI), which was categorized into four groups: low weight, normal, overweight and obesity. Results: Eighty children with a mean age of 6.2±0.8 years were included, being 47 girls (58.8%). The analysis of the anthropometric indicators identified that 26.3% of students were overweight and 15% were obese. The children had averages below the reference values considered for their age range in conditions III and VI. There was a negative association between condition V and BMI and a positive association between values below normal in condition VI with overweight and obesity. Conclusions: There were associations between excess body weight and values below normal in some balance conditions, indicating that the anthropometric indicators interfered in the children's postural balance.

This study aimed to analyze neuromuscular variables (vertical jump and torque in external/internal shoulder rotation) in advanced and novice judo athletes, and to identify which neuromuscular variables allow for discrimination between them. Thirty male judo athletes participated in this study: 19 novice and 11 advanced athletes. The judo athletes performed the external/internal shoulder rotation in an isokinetic dynamometer and the countermovement jump on a force platform. Student's t-test and the discriminant analysis were used, with the level of significance set at 5%. The main results showed that the advanced judo athletes presented higher jump height (p=.03) and power output (p=.02) compared to the novice athletes. In addition, internal shoulder rotation peak torque was higher in the advanced judokas compared to the novice judokas (p=.04), and the ratio between external rotation torque and internal rotation torque was higher in the novice judokas compared to the advanced judokas (p=.006). In this discriminant function, the variables with higher discriminatory power were (in descending order): jump height, internal shoulder peak torque, and ratio between peak torques. The results of the present study demonstrated that advanced judo athletes presented better performance in vertical jump, internal shoulder isokinetic torque, and ratio between external/internal isokinetic torques than novice athletes. The variables used to discriminate between advanced and novice judokas may provide coaches with a guide for sport-specific training needs. [ABSTRACT FROM AUTHOR]

Introduction: This descriptive study aimed to analyze the relations between posture changes, time of practice, number of injuries, impact magnitude in the knee and ankle in landing of thrown technique in handball. Materials and Methods: Nine university athletes with average of age 22.2±1.4 years and time of practice 7.1±2.7 years participated in this study. A questionnaire, the PSU postural evaluation and a tri-axial accelerometer were used with instruments of measure. The dates were collect in the UFSC Biomechanics Laboratory and were analyzed through descriptive statistics and no-parametric statistics. Results: The results showed that: for posture changes, 4/9 athletes had knee flexuous and 3/9 had feet abducted; for the injuries, the knee (5/9) and ankle (3/9) were the body segments affected; the correlations between number of injuries and impact magnitude in the ankle - axel z (rc=0.64) and between posture changes and impact magnitude in the ankle - axel y (rc=0.71) showed statistics significance. Conclusion : The athletes had knee flexuous and feet abducted; the impact magnitude can be considerate how injuries mechanism, as well as a intervenient factor in the posture changes of the handball athletes.

Introduction: Many health changes are related to how individuals respond to work events that are influenced by organizational, physical, and human factors., Objectives: We aim to evaluate the mental workload, the manifestation of musculoskeletal disorders, the associated factors, and their relationships among international transport truck drivers., Methods: This is a descriptive, cross-sectional diagnostic study of 70 truck drivers who entered the intermodal terminal of the city of Uruguaiana, state of Rio Grande do Sul, Brazil, in January 2021. Participants completed the NASA Task Load Index questionnaire and the Nordic Musculoskeletal Symptom Questionnaire, along with questions about work characteristics and health care., Results: The results showed that most truck drivers have a high mental workload (90.0%) and have experienced musculoskeletal symptoms in the past 12 months (72.9%). In addition, this occupational group has characteristics that are predictive of health problems, as most work over 10 hours a day (61.5%). The results also show a correlation between mental workload, hours worked, and lower back injuries (p < 0.05). There is also an association between hours worked and the occurrence of musculoskeletal disorders in the neck, shoulders, and lower back in the past 12 months and in the shoulders and lower back in the past 7 days, especially for those who work over 12 hours a day., Conclusions: The population studied had a high mental workload and a high prevalence of musculoskeletal disorders as well as occupational characteristics predictive of harm to both physical and mental health., Competing Interests: Conflicts of interest: None

Objective  The present study analyzes ankle mobility and lumbopelvic muscle mobility and resistance. In addition, it identifies factors associated with musculoskeletal pain in young ballet dancers. Methods  This is a quantitative, descriptive, cross-sectional study evaluating 14 ballet dancers aged 12 to 16 years old. We used the following instruments: a) Nordic Musculoskeletal Symptom Questionnaire (NSQ) for musculoskeletal pain assessment; b) leg lateral reach test, lumbar lock, and rotation test (for trunk mobility analysis) and lunge test (for ankle mobility evaluation); c) front bridge, lumbar extensor, and lumbar flexor muscles tests to assess lumbopelvic complex resistance. Results  The main complaints reported by ballet dancers were pain in the low back area and in the lower extremities, especially in the knee (57.1%). Those with low back pain had significantly lower lumbar mobility ( p  = 0.05) and lower ankle mobility on both sides ( p ≤ 0.05). Dancers with knee pain presented significantly lower muscular trunk extensor muscle resistance ( p  = 0.05). Conclusions  Our study revealed significant associations between the lumbopelvic complex function and musculoskeletal symptoms, supporting the implementation of preventive strategies., Competing Interests: Conflito de Interesses Os autores declaram não haver conflito de interesses., (Sociedade Brasileira de Ortopedia e Traumatologia.
